l l Specification of Letters Patent. Patented Apr. 26, 1910.'Application :nea November 22, 190e. serial No. 529,283. i

To all whom yttfrmiy-concer/n:

Be it known that I, WILLIAM H. KLUGE,

vacitizen of the United States, residing at Indianapolis, in the countyotMarion and State of Indiana, have invented certain newy and usefulImprovements in Coin-Controlled Indicators, of vwhich the following isaspeci- .coin of proper denomination, and the object of .the invention is'to provide an indicator -which will be controlled by the same coin thatcontrols the lock so as to indicate Aat all times whether the room is-In use or whether it is not in use or -O en I accomplish the objects othe invention by the mechanism illustrated in the accom panying drawing,in which- Figure 1 is'an e ge-view of a portion of the door equippedwith my improved lock, the view showing parts broken away and linvertical section t0 illustrate the indicator mechanism. Fig. 2 is adetail in front view of the door showing the dial of the indicator inits In use like view showing the ial of the indicator in Open position.Fi 4 is a vertical section o-i'jY my improved l'oc detached from thedoor, and taken on the line 4-4 of Fig. 5. A5 is a front inside view of.the lock with the inner'plate of the case or housing removed, the viewshowing the bolt and mechanism for controlling the indicator inpos`ition ready to receive a coin. Fig. 6 is a horizontal section ontheline 6-6 of Fig. 5, showing the parts in vthe same relative positionas the same are illustrated in Fig. 5, and Fig. 7 is a front inside viewof the lock with the inner plate removed, similar to the showing in Fig.5, but on a somewhatlarger scale, and representing the shot-in positionof the bolt and showing the coin indicator mechanism in the positionswhichthey assume when the dial is In use Like characters of referenceindicate like partsthroughout the several views of the' drawing.

8 represents a door to which my lock .is applied. The mechanism ofthelock is contained Within a sheet-metal casing 10 which is fastened tothe door by means of screws 9.

The casing-10 comprises an outer plate 12` osition. Fi .3 is a Ithe bolt'16. through the casing and also through thel having integral ends and`sides'll at ri ht angles thereto, and an inner plate 14 which isremovably secured to the casing.

The main bolt of the lock is shown at -16,

the body of which is a't and comparatively thin and bears against theinner side of the' plate 12. One end of the bolt is reduced in. width toform a part 17 which is projected through a suitable opening in the side11.

vTheopposite end of the bolt is also reduced in 'width to form shoulderswhich will arrest the loutward movement of the bolt, and this end 'ofthe bolt is thickened to form the part 19 which passes'through theadjacent side 11 of the casing to engage a striking-plate (not shown).This endD of the bolt is beveled as shown at v20 for the usual purpose.The increasein thickness at this end of the bolt provides a shoulder 21.A lever 23 having an upper bent end 22, is mounted on a shaft 24. Theshaft 24 is supported bythe two plates 12,and yla of the casing andextends outside of the casing and througlrithe door,

and Vterminates with a handle 26. The bent end 22 of the lever isattached to one end'of a spirally wound spring 27, and the opposite endof-said spring is attached to a lug 28, which lun is a part of abearing-plate 29 supported by the plate 12 of the'casing. The end of thebent portion 22 of the lever 23 is held in constant contact with theshoulder1 21 bythe spring 27 and the bolt is normally held in outer shotposition by the tension. of said spring 27..-

Supported by the upper end of the lock` :casing ,is a coin chute 30, thelower end of which discharges Within the casin above This chute extendso liquely door 8 to a suitable slotted escutcheon 81.

Mounted on thebolt 1G so as to be directly under the discharge end ofthe 'chute 30 when the bolt is shot out in its locked position isacontinuation of the chute, the upper end of which will preferably beexpanded into 'a funnel to insure the accuratedeliveryof the cointhereto from the the upper chute '30.

An angle plate 35 is secured to the plate 12 I of the casing-and theupper horizontal memberof said angle plate, projects across thevdischarge end of the chute extension 33 far enough to keep a coin fromdropping out of l said chute extension while the bolt is in its outer orlked position. The chute eXtension 33 has a transverse notch 39 in itslower end (shown in dotted lines in Fig. 4) which will permit theupperend of the lever 23 to travel through said chute extension, except whenits travel is prevented by the 4presence of a coin 37 in said extension.When the notch 39 isl closed by the presence of a com in the part 33 thelever 23 by contact with the coin will shoot the bolt 16 inwardly of thecasing thereby unlocking the door, and

" as soon as the bolt moves far enough to cause the coin to pass 'theend of thesangle-plate i bracket 35 the coin .will be free to drop by'gravity as shown by dotted lines in Fig. 4. The throw of lever 23 isarrested by the contact of its lower end against the lug 28, and

a person manipulating the knob 26 will invariably release the knob uponthe arrest of the lever by its contact with shoulder 28 so that, if thecoin has not beenpreviously released, it will be upon this occurrenceand will drop tothe bottom of the lockcasing into a suitable' receptacle41` placed fthere to receive it. l 1

-42 is a ykey mounted in the lock-casing so as not to beremovabletherefrom and having its stem extending out through the door 8 andsquared to lit the socket of a removable 'extension carried'b'y a porteror other attendant who is required to enter the room fre uently for thepurpose of cleaning same" or or other reasons. The bit oi the'key entersa suitable notch in the bolt 16.

Supported by the loclocasing between 4the bolt 16 and plate 14 'andparallel with the bolt 16 is a plate 43 which has a tongue 44 formed outof the body of the plate andv turned up parallel with said body to forma support and guide rfor a sliding rack bar 45. The inner edge of theplate 43 is bent out at right angles rto form the lange 46 `and thisflange is slotted opposite the tongue 44 to permit the passagetherethrough of said rack-bar 45. The plate 43 adjacent its lower vupper end of which is in contact with the'- edge, is provided with aslot 47, and pivotally mounted on the plate 43 is a lever 4S, one end ofwhich crosses the slot 47, and the i outer end of the rack-bar 45. -Theopposite or inner end ot the rack-bar 45 is adapted to contact with acoin 37 in the chute-extension ",'133'when the bolt 16 is shot inwardlyas y previously described by `the action of lever 23 as rocked by theknob 26.

Supported by the plate 14 and plate 43 is a spindle 50, and mounted onthe linner end' of this spindle is a pinion 51, the teeth of which meshwith the teeth of the rack-bar 45, whereby, when the rack-bar is movedlongitudinally by Contact therewithof a moving coin, as above described,the spindle will be rocked. The outer end of the spindle50 has a squaredsocket to receive the square stem of a circular dial-plate 52.. Thisdial-plate isanounted on the outer face of the door and is thereretained by acovering plate 53, hav- I' ing a half-circle opening 54through which a'corresponding portion of the dial-plate 52 is exposed toview. Thedial-plate 52 bears the inscription In use on one ortion of itssurface and the inscription pen on .an opposite portion of its surface,and these 1nscrlptions are brought alternately Vinto view.

through the opening 54. When the meehanism is in the position'shown inFig. 5 the vdial 52 will expose the word Open through the opening 54,and when the mechanism is arranged as shown vin Fig. `7A the words Inuse will be visible through said opening. In order to -prevent theexcess movement of the dial-plate 52 the pinion 51 will have4 a blank 60in its cogged portion to form alock by contact with the rack-bar.

Located between the bolt 16 and the plate 43 is a bar 62 havingadownwardly extended arm, 63, the end of which is bent at right angles toform the part 64 which extends through the slot l47 in the plate 43 farenough to contact with the lower end ofl the pivoted. lever 48. Oney endof the bar 62 extends outside of' the lock-casing and is provided' witha knob 65. The extension 17 of the bolt 16 has a longitudinal slot 66,`

through whichthe knob 65 is passed, and because of the slot 66 a limitedmovement of the bolt 16 is permitted withoutmoving the bar 62. After thebolt 16 has been shot v in to the position shown in Fig. 7 and theindicator mechanism moved substantlally to the position there shown, thebolt will'be returned. by the action of spring 27 through door, and atthe same time the projection 64 by contacting with lthe lever 48 willref turn the rack-bar 45 to the position shown in Fig. 5 and return thedial` to position exposing the Open inscription. The bar `6,2 will .bereturned to the position shown in4 Fig. 5, with the return of the bolt16, by the. action of spring'27. The indicator will then show at Openwhich proclaims'that thev room or booth is available for occupancy.
